[Partly Solved] Oscam SAT-IP Descrambling only works if start the channel via VLC first

g gebruikerh · 2019-06-13T20:17:41+00:00

Hi All, After a few day testing trying etc, I got the SAT-IP connection to my Panasonic client working:). But now I have an issue with my descrambling. I h...

Try to increase debug logs in TVH
Configuration > Debug

tbl-satip, rtsp, satips

maby and some others

My guess is that TVH pass stream without descramble

maby issue ticket need to be created
Somehow


HDhomerun > TVH Sat>IP server > Sat>IP client

skip descrambling or url used to call stream is wrong.

Hi Saen,

So i'm log file attached. It looks like you are maybe right that somehow not triggers oscam to start decrambling or are you seeing something else?

Is there any setting for hdhomerun in tvh?

zapp -it

[First of all, English is not my native language :) ]

I don't know if this applies to this question, but okay, not shot is always wrong. I have a provider that offers replay TV and uses an RTSP stream for that, I cannot add this stream in TVH because the provider first expects a DESCRIBE command instead of a SETUP command. Now I have just looked in the RFC 7826 and I see in the examples (https://tools.ietf.org/html/rfc7826#appendix-A) that they indeed first send a DESCRIBE command for the SETUP command, I want not to say that this could be the case here but this information is more under the guise of FYI ;)

Hi Saen,

See screenshot attached I see no setting for SAT>IP for HDhomerun. Maybe it's the combination that not works? HDHR, TVH, SATIP?

Although my internal WETEK tuner has the same problem.

Or may Zapp-IT information could be correct? But I can't explain why FTA channel do work and decramble channels not..

Or is there maybe something wrong in my network?

Select option removeScrambled bit TV is stupid and do not try to play if bit not removed from stream

Hi Saen,

Did not help. Only difference is that TV is giving me the info "no image" instead of channel encrypted.

Oscam is giving me this info:

If look at the TvH log it looks like in a split second it give info to Oscam to start de-crypting, but also give the info to stop the de-crypting. Than it stil keep sending a stream to the TV, but no decoding has been done. Oscam wil start again but the information is not add to the stream anymore. So it looks like an issue. I think Tvh but it also could be Oscam.

What do you say?

Maby some play with oscam needed also

Else we can organise TeamViewer/Anydesk session to test some other things.

Hi Sean,

Thanks for input. I will keep on trying and play with Oscam to see if I can get it working. Do some more reading.

And maybe we can do a teamviewer session to see what is happing. It strange it seems that more people use the same kind solution as me. But al do have slightly different set-up, than me and have different problems....

I even installed the solution on my Synology NAS yesterday.. same issue..So it not hardware depended as far as I can see.

That option is only for the source and is for the case when the source has descrambled the stream, but did not unst the scramnled bits. (If I remember correctly, the origin of this option was that a CI+ module which was doing this.)

If this option is checked for a source which IS NOT decrypting, it will cause tvheadend to not try to decrypt because it will assume it is already decrypted.

So, with it set, tvheadend is just sending the encrypted stream with the encrypted bit unset, which the tv sees as garbage...

Maybe a trace of descrambler and capmt would be helpful.

You can also try to increase the "Configuration->General->Base->Descrambler buffer (TS packets)" which may help if there is a slight delay in getting keys.
